Quality evaluation of cut roses by stem's curvature (Part 2): reconstruction of 3-D stem shape

摘要

It is necessary to reconstruct a 3-D stem shape for evaluation of a stem curvature quantitatively. A 3-D stem shape was reconstructed using rotary motion of a stem on a rotary table. The rotary motion was expressed by many 2-D stem shapes using many pictures, which were taken from different angles. The 2-D stem was extracted well by the difference on color histogram as well as the shape difference between the stem and the leaf.
